Alexxandr [17]

Answer:

x = -3

Step-by-step explanation:

The line parallel to x=8 is another vertical line:

x = constant

To make it go through a point with an x-coordinate of -3, the constant must be -3.

Your line is ...

Write the equation for:

xenn [34]

Answer:

$\frac{1}{2} x +x = 2 (x-4)$

Step-by-step explanation:

Suppose number is x

Following equation can be written from question statement

$\frac{1}{2} x +x = 2 (x-4)$

Simplifying it further

$\frac{3}{2} x = 2x-8$

$\frac{3}{2} x -2x=-8$

$\frac{3x-4x}{2}= -8$

$-x= -16\\x=16$

Solve 2cos x+2cos 2x=0 on the interval [0,2pi)

rjkz [21]

$2cosx+2cos2x=0 \\ -2sin^2x+2cos^2x+2cosx=0 \\ -2(1-cos^2x)+2cos^2x+2cosx=0 \\ -2+2cos^2x+2cos^2x+2cosx=0 \\ 4cos^2x+2cosx-2=0 \\ t=cos x \\ 4t^2+2t-2=0 \\ \Delta=4+32=36 \\ t_1= \frac{-2-6}{8}=-1 \\ t_2= \frac{-2+6}{8}= \frac{1}{2} \\ cos x=-1 \lor cos x= \frac{1}{2} \\ x=-\pi \lor x= \frac{5\pi}{3}$
